The following are methods of filling engraved plates. (1) Fill up the cuts with finely powdsred sealing-wax of the colour required, press down, and see that but little of the wax is left on the surface of the plate. Warm the plate gradually until the wax is melted, and put aside to cool. Then finish with a Tam-o'-Shanter stone to remove any wax left on the surface of the plate, and polish with oil and flannel. (2) Some engravers prefer grinding the sealing-wax in gold size, and, when the plate is filled in and set, polishing with alcohol. (3) Dissolve sufficient black or red sealing-wax in alcohol to make a thick paste, and fill the engraved lines. When the alcohol is evaporated the wax becomes hard.
